WP-6: Establishing of databases and submodel testing and adaptation in the Chirchik basin


  • Establishment of zoning criteria and zoning of non-irrigated and irrigated basin area
  • Creation of basic thematic GIS layers, which must be linked with database by using of special unique codes for GIS objects of Chirchik river basin
  • Establishing water resources database (surface and ground water location and structure)
  • Organize observation, assessment and prediction of water availability in Chirchik river basin based on established network
  • Adaptation, interconnection and testing submodels for surface (HBV/MONERIS/QUALIE) and ground water resources (MODFLOW) amount and quality management of Chirchik river basin
  • Development of models for water resources management facilitating restoration and maintenance of ecological stability in Chirchik basin (CASIMIR)
  • Establishing database on water demand (municipal, industrial, agricultural, hydropower sector) WEAP
  • Assessment of perspective socio-economic development sustainability starting from scenarios of perspective development (pricing policy in agricultural sector, investment distribution)
  • Establishing database on land resources (climate, soils, land coverage/use, SLISYS)
  • Selection and adaptation of mathematical models to study impact of water supply on physical, economic and ecological indicators
  • Establishing database of agricultural inputs, production and pricing indicators
  • Selection and adaptation of mathematical models (EPIC, GAMS-Chirchik, WEAP) to study impact of water resources distribution strategy on subjects of Chirchik basin (agricultural production, industry, municipal needs)
  • Development and testing sub-model of decision-making process on water resources management at national and basin level
  • Establishing an overall project database for the Chrichik basin

Description of work

In the case of the Chirchik basin databases about land resources, water resources and water demand and will be established in the same structure as done in the Neckar basin. On the basis of the topographic and thematic maps of 1:100.000 (or 1:200.000) scale as well as Landsat-7 ETM satellite images, a database with basic spatial geometries will be gathered. Available water resources and their quality will be assessed, including evaluation of perspectives with regard for possible climate changes. For that end, the mesoscale hydrological model HBV and the groundwater flow models MODFLOW/MODPATH will be used. Anthropogenic load on natural ecosystems of the basin in flow formation and dispersion zone will also be assessed and modelled (MONERIS/QUALIE/WASP). In addition, the fish production complex effect on river ecological state will be studied. Data on hydrological, hydrochemical and biological parameters characterizing ecological and economic state of ecosystems will be collected and analyzed for water resources database establishing. Furthermore, a land resource data base including data about agricultural inputs, production and pricing indicators will be provided (EPIC/SLISYS). Natural, socio-economic, and environmental characteristics of the basin will be analyzed in order to identify similarity criteria and implement zoning. Water demand models (WEAP) will be applied to develop future water resources consumption scenarios. An economic model (GAMS) will be adapted for its use in the integrated model and account for socio-economic aspects of perspective development, in particular, their impact on pricing policy and investment distribution. Together with the basic GIS layers an overal project database for the Chirchik river will be established.
